Professor Skinner applies science, satellites, and surveillance to fishing. This channel is the best. You can’t watch and not learn how to be a better fisherman. Thanks John.

I’ve soaked the orange foam ear protectors in gulp juice and put them on a baited hook and it was noticeably better then bait alone.

Great experiment John. Proof that you can take the boy out of the lab but you cant take the lab out of the boy. Rather than a fisherman who loves science, I believe you are a scientist who loves to fish and is particularly good at it. Well done my friend.

[@artkitzmiller957]

I thank you for confirming that the non-Gulp baits that I have been putting into my Gulp bait container was a waste of time, money and numbers of fish caught. That being said, I will not be drinking any beer that John is offering his guest in clear Solo Cups! =)

Hey John, love the way you (old scientist/engineer??) approach these questions as I am an older scientist/fisheries biologist. You really have the feel for isolating variables. What impresses me even more is your "followers" have a really great sense for setting up an experiment and understanding how science works. You probably have the most scientific following of any fishing site that I follow. Keep up the great work!

[@nextdriftfishing]

Great video John! We too noticed that our old batches out performed the new ones. Probably supplier changes/ the mountain yams they're made from have changed. We even tried throwing them in the microwave and cooking them in the juice for a few seconds. Interesting stuff.

[@matt9822]

After years of gulp usage, I can say pretty confidently that the 6" pink/glow jerk shad will outperform anything for NJ ocean flounder fishing. Traditional grubs always work well but the shads get more strikes, they dart left/right when jigged, it triggers that reaction strike better, look how many videos you have of them just trailing the grub without striking. Agressive big jigging the jerk shads is way out preforming the slight jigging bumping it along the bottom technique with the grubs on my boat.

[@karlneumann6833]

[@joedennehy386]

I find this so interesting. Been using gulp here in New Zealand for snapper which are like giant versions of porgies up to 30lb. Colours and shapes vary on the day, depending on light conditions I suppose. But casting forward of the drift for us is the most important method for big fish, ten pound plus. The.most popular here is 5 inch jerk shads, nuclear chicken. My favourite is new penny. But for us it depends on the day

This was a great video & experament & I love when people use there minds to make sense of what makes things work. It shows that the gulp grubs do absorb liquids, But the dye is a different makeup than the gulp juice & maybe present for longer than the gulp juice because it is a dye. Bravo!

[@sammyvh11]

Gulp is a game changer in fresh and salt water. I fish almost daily for Crappie and started using it years ago and increases your bite rate significantly.

[@1cryogen]

I started out with gulp using the 4" swimming mullets. Particularly with the chartreuse, the tubs always were much duller and a little firmer. The package gulps were always bright and shiny, they seemed softer and more fragile. Obviously they were different recipes; no way that was just different batch issues as this persisted over years. Probably marketing. Gotta keep those 8$ packages shiny. They certainly are effective baits, though. Great video John, a smart, thought provoking experiment.

Theoretically the grubs would go through osmosis practically for as long as youre using the bait. Since it would constantly be going through a process of having as much water and dye equivalency in itself as its surroundings would allow. Pretty cool stuff. Well to have polymers available to the public that do that constantly. Scientific proccess is pretty wild.

Doing this is very informative for me as I'm looking to catch my first fluke next year. But it's also R&D work for Berkeley, i hope they notice this and at least recognize the work you did here. It's valuable for them, too

[@Lauranyyfan]

Awesome video, John! Our fluke group of guys always ponder stuff like this. There have been times where I've used the same grub (because it was so successful) until it couldn't stay on the hook anymore. Sometimes with keeping it in the gulp juice and sometimes just dropping it right back and still having great success. So, your video does prove how tje scent does last. Obviously, it would be stronger when freshly taken out of a pack, but perhaps the fluke's ability to smell might be much stronger than we know, making even small amounts of leaching enough to attract them!

[@teampenn2007]

This is a great test. Thanks. I have some generic plastics along with Berkely Power Baits. And I was of the mindset to drop the generics into the Gulp Juice to charge them. But after watching this, it seems the generic PVC baits are so non-porous that they don't take a charge. Great info.

[@mbnz0174]

I replicated your experiment with Slam Ultrabite softbaits, a long out-of-production and failed Gulp competitor made in Australia I believe. They are also biodegradable and have an appearance similar to Gulp, but weren't successful because the material was perceived to be too rigid to produce a nice action. Anyway, after a night soaking in Gulp juice mixed with dye, the dispersion was very similar to that of Gulp! Since my primary use for these softbaits is as a trailer on jigs, I think they will be perfect, but the main advantage is that they're $1 in the bargain bin instead of $13 a packet for Gulp. Thanks again for this video.

[@asantigarcon]

Great experiment John. I've noticed that firmness differs on some colors too. For me the 4 " mullet is my go to-the white glow is much firmer than green. I'd be interested to see how the colors dry out at different rates...

[@JohnSkinnerFishing]

Exactly on the firmness difference among different colors! It's exactly why I did this. BTW, if you like the mullets, try the 4'' grubs. I find those are even better.

[@tomterrific2018]

John I have to agree GULP has changed the game..an amazing product..one down side..more so on the small sizes..tail biting..on the smaller sizes I’ve switched to Z-man with Pro Cure.. any comments? Very helpful channel..thanks

[@JohnSkinnerFishing]

The tail biting is even worse on the big ones, because it gets expensive when seabass are biting those grubs that cost a couple of bucks apiece. My personal experience with ZMan vs Gulp was that both might work evenly on snook, but for me, Gulp 5'' jerk baits outperform for reds and trout on the flats. I have been in places though where there are just so many pinfish that using Gulp is pointless.

[@thomaslawrence3232]

Maybe next time forget the dye and use a volt meter to see how well each of the cups of liquid conducts a weak electric charge. Great video. I can't wait to show this to my students.

[@17yrsofcollege]

Indeed. Is the solution more or less saline?

[@JamesCasatelli]

Should try it again with salt water from where you regularly fish. It could affect the uptake of juice if it's covered in salt when you go to recharge it between drifts. Neta experiment though, definitely good info to keep in mind.

[@JohnSkinnerFishing]

I think the results would be the same in terms of how the grubs take and disperse the colored juice in relation to each other. If there is any difference salt/fresh I would think it would be in the rate of dispersion and uptake.

[@calallen8786]

In Florida we really don't use gulp. But I find that procure is more effective. The stores and few tackle shop put gulp stuff even the juice in the clearance section.

[@gene10846]

Great experiment. Blows away my suspicion that the juice leached out quickly. Another issue is - do gulp get stale if you keep them around too long? I started putting all my gulp in a sealed container because I was tired of leaking packaging and mixing them all up. figured it was all the same juice. I did this for a couple years and then wondered if I was adding good fresh gulp to old stale juice. I don't have an answer but I stopped mixing prior year's gulp with this year's gulp. I did some online searches but never found a conclusive answer. p.s. I will be down in Charlotte Harbor next week for 3 months. I will keep an eye out for you.

[@JohnSkinnerFishing]

Gulp seems to last forever. I had some very old packs with brown juice and they actually seemed to catch better than the fresh stuff.

[@davidkuperschmid5274]

Watching another of Skinner's great videos this evening, I thought about soaking pork-rind in gulp juice. Or pork-rind perforated with a thousand pin pricks to increase absorption. Great action, indestructible compared to Gulp, someone must have tried it before.

[@fireman194]

Excellent video. I’m wondering though if the water was salty like the bay, instead of tap water, would that have any effect on the rate of leech.

[@viper2788]

Thanks for this test john, very interesting stuff!

[@tb9187]

I wonder if it’s not length of time where it will disperse, but how efficiently it can dump the scent initially. If that first round was difficult to parse because it was all very saturated, it’s possible that the softer (presumed to be higher performing) dumped a greater amount of scent initially and then *still* hung on and kept producing after the various water changes. If so, it’s possible that the theory still holds that it could outperform, since it could be putting out more scent on that first part of a drift after a drop. You note how important the recharge is because the initial dump of scent matters-maybe that initial cloud of scent in combination with the long lasting trail that either firmness produces is the key to the perceived difference in performance. We know from your videos that fish will follow a scent for a long ways, so that initial cloud of scent being strong could matter.

[@Thefish613]

I agree with you! Another thought was, these tests were done in cups, which released only a bit at a time to make an even saturation between gulp and water. What about putting each one in a bucket? Will it leach out at different speeds as you (and I) are hypothesizing?

[@jeffreypetersen6149]

Here is a test for you, put gulp in juice, in a jar that can be drawn into a vacuum. See if bubbles come out of the baits hence scent goes in when it is released.

[@outdoors-fun]

A good test would be rate of absorption. Drop them in the dye for a couple minutes (as we would to "recharge"). And then drop them in the fresh water.

[@HobbiesHobo]

Excellent info. Really enjoyed watching that. Thanks, Mike.

[@17yrsofcollege]

I didn’t catch it perhaps but was the sample water used fresh water? I believe that the Gulp Juice is high in salinity. Perhaps the rapid leeching of the gulp juice visualized in the test was due in part to the tendency for the mixture to obtain a passive homeostasis in salinity. Ie. The fresh water rushes into the gulp and salt rushes out. It was just a variable I considered. Really interesting Stuff John.

[@JohnSkinnerFishing]

I used fresh because I was initially trying to compare grubs, and the water shouldn't have mattered.

[@BobelPop]

One thing I've learned is that Gulp baits are made of a water based resin which is why they absorb & disperse more juice. Many of the plastics are oil based like the Power Bait & don't perform as well with Gulp juice. Pro-Cure gel would be better for the oil based gummies.

[@JohnSkinnerFishing]

That's my understanding too.

[@idkwhattouseforname]

Hey John! Good experimental design. I have a background in biochemistry and I have a few comments. I do sense one potential flaw. Although the dye does get mixed into the gulp juice, it may embed and leach from the gulp juice at a different rate than the scent itself. So while the grubs were still dispersing the dye at 1 hour, that does not necessarily convey that there will be scent dispersing at that one hour mark. Differences in chemical structures of individual molecules will cause them to migrate in and out of the grub at varying rates, even if both molecules are water-based (polar compounds). What the experiment should still be able to tell you is the relative differences between grubs. A slower rate of dispersion of the dye should also correlate to a slower dispersion of the scent.

[@JohnSkinnerFishing]

Thanks, and it was that comparison among the grubs that I was initially looking at. Since the Gulp juice was dyed, I've got to think there is some correlation between color and scent dispersion. If I don't dye the juice, it's hard to see what's happening.

[@idkwhattouseforname]

@@JohnSkinnerFishing Thanks for the reply. I bet someone could test the duration of the scent release by doing a serial dilution like you just did and then sipping the water!

New Zealand snapper fisherman here (snapper = HUGE porgy). This video confirms what I already know. The scent in Gulp is key to getting bites. I was catching snapper on chunks of Gulp in dirty harbour water the other day. Baits were getting smashed straight away. In contrast, Zman soft plastics of all colours got very little attention. This isn't a criticism of Zman, they are very different products. Just a shame Gulp aren't more robust.

You should dry out the grubs so they shrink (get a dry weight) than soak them until they puff back up and get another weight... That will really tell you how much each grub holds

[@brendan8363]

I love nerding out on fishing! Great approach. But I do think it’s a big assumption that the scent and the dye will uptake similarly… wouldn’t be surprised if the scent is oil based whereas the dye is water based. Could be a very big difference in results if you tested an oil-based dye? Great channel, John. Thanks for educating us.

[@JohnSkinnerFishing]

Good thinking, but Gulp juice is definitely water-based. That's why it washes off the PVC grubs so easily.

[@brendan8363]

@@JohnSkinnerFishing Ahh. I bet you’re right. I’d suspect that a drop of straight gulp juice in a cup of water would sink. Or disperse, not float. And they wouldn’t include hydrogenated oils because there’s no solidifying at cooler temps. Plus one for your results!

[@patcurcio1379]

Thank you, John. As always, a very informative video. One question… how do we know that the leaching continues to be gulp juice, and not just the dye bleeding? Is it possible that the gulp juice was washed away in the first round, and only the dye remained? That would certainly justify your recharging and catching more fish on a recharged gulp compared to a gulp that was not recharged.

[@JohnSkinnerFishing]

The solution was mostly gulp juice, and there was no visual separation between the dye drops and the gulp juice, like you would see if you tried to mix oil and water. The juice and dye droplets are both water-based, so given the uniform appearance of the two combined, I'm pretty comfortable that you're seeing colored gulp juice bleeding, not just dye.

[@redwood1957]

Lots of variables in this, I great job. I wonder if dying would replace the juice red is my choice 🤔

@@JohnSkinnerFishing hi John, to follow up on your comment. Does this test really measure the “intensity of the dispersal?” I think it covers duration, but how fast is one really dispersing over another? Couldn’t rate of dispersion be the key factor in one grub outperforming another, especially where strong currents and water movement, like out at Montuak, whisk it away rather quickly. Maybe the effectiveness isn’t the duration of the leach but the initial intensity that attracts the fish to the bait. Just a thought, either way love your channel, thanks.

[@troyfairweather8553]

Also I bet if you try squeezing out the gulp with a rag before charging it may work better to. This should get some water out of the gulp to fill back in with juice. Wonder if salt water would have made a difference I your test, gulp seems to work much better in salt water then fresh.

[@TheReallyRealReel]

There's a much more simple way to test absorption rates. Weigh them before you drop them in un-dyed gulp juice, and weigh them after. Un-dyed so you can be 100% sure which one is which.
